I have seen posts from people about the water on the dome grooves & how they are trying to stop it. I just wanted to let everyone know that I have the dome cover & it has been on the dome for about a week but yesterday was the first rain we have had.
The rain was long (all day) & a few time it was pretty hard. I checked & the wasn't any water in the grooves. I didn't think there would be because the cover comes about 8" below the dome/wall. It also covers the top of the door. This may be a problem for anyone who put in an awning.
So this would be another option to keep water out of the grooves but the are a couple of trade off.
The cover will only fit right a certain way. If you hold it up & look at it it has a center panel & curved sections coming off it. Just like the dome design. It also has to go on the same way each time so the hold downs line up. The NexDome marking on it needs to be about center in the shutter. This limits where the hold downs will go & two of mine lines up with one of my bays. I put my bays in weird spots.
I don't know if it matters but I have the shutter with the wheels, the old design. It may be easier to install/remove the cover with the tracked shutter. That was the main reason I bought the cover to protect the wheels of the shutter.
1: Putting the cover on & taking it off isn't the greatest. The underside is somewhat tacky. It would have been great if it was lined with nylon. I don't have a problem as my dome is on a patio & the is a 2' wall I can put the cove on from.
2: You would need to install something for the hold downs. I just put eye hooks into my walls. There are 8 hold down spots.
3: You would need to by bungee cords for the hold downs.
I would suggest getting a stool like the one pictured if you want to use the cover. I use it even with the wall I have.
